Thanks Jan.
I am using a WGS84 projection (the default geographic projection). Is there
a way to modify the algorithm to work with a non-cartesian CRS? I am not
sure what would be involved.
Would it suffice to convert to Cartesian, collect all of the points, and
then transform back to WGS84?
Thanks,
Cliff

Don't miss this year's exciting event. There's still time to save $100.
Use priority code J8TL2D2.
